What components are tested in a permanent link?

• A. The cable only
• B. The wall outlets
• C. The cable and jacks
• D. The equipment rack

Answer: (C)

Testing a permanent link focuses on the fixed portion of the cabling between the wall outlet and the equipment, including the in-wall cable and the terminating hardware at each end. This combination—cable plus jacks—defines the permanent link because those components are fixed in place and form the actual path the signal travels through without movable cords. Wall outlets alone don’t include the in-wall cable and fixed terminations, and the equipment rack lies outside the cabling path. Patch cords aren’t part of the permanent link either. So the components tested in a permanent link are the cable and the jacks.
